Description

Technical Field

[0001] This utility model relates to the field of power distribution cabinet technology, and in particular to power distribution cabinet expansion. Background Technology

[0002] In modern power systems, distribution cabinets, as core equipment for power distribution, are widely used in critical areas such as data centers, industrial production, and buildings. With the continuous growth of electricity load or the expansion of business scope, the capacity of existing distribution cabinets often falls short of meeting new demands, necessitating expansion and upgrades. The traditional method of expansion involves replacing existing distribution cabinets entirely with larger capacity models; however, this approach is costly, time-consuming, and inevitably causes prolonged power outages, significantly impacting applications that rely on continuous power supply. Utility Model Content

[0003] The present invention aims to solve the problems of complex structure and cumbersome operation of existing power distribution cabinet expansion, and provides a power distribution cabinet expansion solution.

[0004] To achieve the above objectives, the present invention provides a technical solution comprising a housing and a power distribution component installed within the housing. The housing has a first input port and a second input port on its two sides, and the power distribution component is connected to the module cabinet through the first input port or the second input port.

[0005] When the expansion distribution cabinet is applied to a dual-cabinet configuration, the module cabinet can be connected to the expansion distribution cabinet via either the first input port 1 or the second input port, thereby enabling the expansion distribution cabinet to be installed on the left or right side, adapting to different site requirements.

[0006] In one embodiment, two identical sets of power distribution components are connected to two module cabinets through the first input port and the second input port, respectively, so that the two module cabinets are connected in parallel on the expansion power distribution cabinet.

[0007] When the expansion distribution cabinet is applied to a three-cabinet system, both the first and second input ports are connected to an external module cabinet, thereby enabling the expansion of the expansion distribution cabinet.

[0008] In one embodiment, the power distribution assembly includes:

[0009] The copper busbar is connected to the module cabinet through the first input port or the second input port;

[0010] An input circuit breaker is installed above the input copper busbar;

[0011] An output circuit breaker is installed below the input circuit breaker and is electrically connected to the input circuit breaker.

[0012] The output copper busbar is connected at its bottom to the output circuit breaker and at its top to the output connector located on the top of the housing.

[0013] The input circuit breaker can control the on / off state of the overall circuit. In addition, when the circuit experiences overload, short circuit or other faults, the input circuit breaker can automatically cut off the circuit to protect the downstream components. The output circuit breaker can protect and control the on / off state of the output branch circuit.

[0014] In one embodiment, at least two horizontal beams are arranged parallel to each other inside the housing. The input circuit breaker is installed on the upper horizontal beam, the output circuit breaker is installed on the lower horizontal beam, the top of the output copper busbar is connected to the upper horizontal beam, and the bottom of the output copper busbar is connected to the similar horizontal beam.

[0015] In one embodiment, a cabinet door is installed at the front end of the housing, and a display screen and an emergency stop button are installed on the cabinet door.

[0016] In one embodiment, the module cabinet includes a mounting frame and multiple power modules, which are arranged vertically and parallel to each other on the mounting frame. The power modules are connected to the power distribution assembly through the first input port or the second input port.

[0017] In one embodiment, a plurality of input AC copper busbars are mounted on the mounting bracket located at the rear of the power module, and the power module is connected to the power distribution assembly through the input AC copper busbars.

[0018] In one embodiment, a plug connector is mounted on the mounting bracket near the rear of the power module, and the rear of the power module is plugged into and detached from the plug connector.

[0019] In one embodiment, the power module is equipped with a cooling fan and a handle at its head.

[0020] In one embodiment, an exhaust fan is provided on the top of the mounting bracket.

[0021] This utility model provides input ports on both sides of the expanded power distribution cabinet, and two sets of input and output power distribution components can be installed inside the cabinet. When the expanded power distribution cabinet is used in a dual-rack configuration, the input port on one side can be selected according to the actual scenario and connected to any set of internal power distribution components to adapt to different site requirements. In high-power demand scenarios, the expanded power distribution cabinet can be expanded into a three-rack configuration, with input ports on both sides and the two sets of internal power distribution components connected to the modular cabinet. This achieves the expansion effect without changing the overall structure of the expanded power distribution cabinet, resulting in a simple structure and convenient operation.

[0037] To make the objectives and technical solutions of the present utility model clearer, the technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present utility model. All other embodiments obtained by those skilled in the art based on the described embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0038] Please combine Figures 1 to 4 The expansion distribution cabinet 1 provided by this utility model includes a housing 11 and a power distribution assembly 12 installed inside the housing 11. The housing 11 has a generally rectangular parallelepiped structure. A cabinet door 111 is installed on the front end of the housing 11. An emergency stop button 112 and a display screen 113 are also installed on the cabinet door 111. The emergency stop button 112 can stop the expansion distribution cabinet 1 with one key in an emergency. The display screen 113 can display the various parameters and status of the expansion distribution cabinet 1 in real time. A first input port 114 and a second input port 115 are respectively opened on the two end faces of the housing 11 for connecting to an external expansion module cabinet. When the expansion distribution cabinet 1 is used in a dual-rack configuration, the external expansion module cabinet can be connected to the expansion distribution cabinet 1 through either the first input port 114 or the second input port 115, thereby enabling the expansion distribution cabinet 1 to be installed on the left or right side, adapting to different site requirements. When the expansion distribution cabinet 1 is applied to a three-cabinet configuration, both the first input port 114 and the second input port 115 are connected to the external module cabinet, thereby expanding the capacity of the expansion distribution cabinet 1. Multiple first cable inlets 118 and second cable inlets 119 are also provided on both sides of the housing 11 near the first input port 114 and the second input port 115, respectively. The output lines of the external expansion module cabinet can be connected to the expansion distribution cabinet 1 through the first cable inlets 118 and the second cable inlets 119. Since the external expansion module cabinet generates a large amount of heat during operation, configuring the expansion distribution cabinet 1 with the housing 11, along with the first input port 114, the second input port 115, the first cable inlets 118, and the second cable inlets 119, not only avoids affecting the electrical connection with the external expansion module cabinet but also isolates the heat generated by the external expansion module cabinet.

[0039] like Figure 3 and Figure 4 As shown, multiple horizontal beams 116 are arranged parallel to each other inside the housing 11 for mounting the power distribution assembly 12. The two ends of the horizontal beams 116 are respectively connected to the two sides inside the housing 11. In this embodiment, the power distribution assembly 12 includes a first input circuit breaker 121, a first input copper busbar 122, a first output circuit breaker 123, and a first output copper busbar 124. The first circuit breaker 121 is mounted on the front end face of the upper crossbeam 116 via an insulator. The first input copper busbar 122 is connected to the bottom of the first input circuit breaker 121 and is located near the first input port 114. It is connected to an external module cabinet via a first input interconnection line 125 passing through the first input port 114, so that the power of the external module cabinet is input from the first output copper busbar 124 to the expansion distribution cabinet 1. The first input circuit breaker 121 can control the on / off state of the overall circuit. On the other hand, when the circuit experiences overload, short circuit, or other faults, the first input circuit breaker 121 can automatically cut off the circuit to protect subsequent components.

[0040] The first output circuit breaker 123 is mounted on the front end face of the lower crossbeam 116. The first output circuit breaker 123 is electrically connected to the first input circuit breaker 121 (internal electrical wiring is not shown in the figure). The first output circuit breaker 123 can protect and control the output branch circuit. The first output copper busbar 124 is vertically mounted on the back of the crossbeam 116. The bottom end of the first output copper busbar 124 is mounted on the lower crossbeam 116 and connected to the first output circuit breaker 123. The top end is mounted on the upper crossbeam 116 and connected to the output connector 117 located on the top of the housing 11. Electrical energy is transmitted from the first input circuit breaker 121 to the first output circuit breaker 123, and after passing through the first output copper busbar 124, it is output to an external DC load device through the output connector 117. In this embodiment, the first output copper busbar 124 is an output DC copper busbar.

[0041] like Figure 5 As shown, when the expansion distribution cabinet 1 provided by this utility model is actually applied to a dual-cabinet configuration, the expansion distribution cabinet 1 is externally connected to a first module cabinet 2. Combined with... Figure 6 The first module cabinet 2 is connected to the first input copper busbar 122 in the expansion distribution cabinet 1 through the first input interconnection line 125, thereby realizing the input of electrical energy.

[0042] like Figure 7As shown, in this embodiment, the first module cabinet 2 is a drawer-type module cabinet, including a mounting frame 21 and multiple power modules 22. The mounting frame 21 includes multiple parallel storage spaces 211, and the power modules 22 are placed in the storage spaces 211. A plug-in connector 212 is installed on the mounting frame 21 located near the tail of the power module 22 within the storage spaces 211. The tail of the power module 22 is plugged into and detached from the plug-in connector 212, increasing the ease of maintenance and installation of the first module cabinet 2. A cooling fan 221 is installed at the head of each power module 22 to dissipate heat. A handle 222 is also installed at the head of each power module 22 for easy removal and installation. When the first module cabinet 2 and the expansion distribution cabinet 1 form a dual-cabinet configuration, one end of the tail of the power module 22 is close to the expansion distribution cabinet 1.

[0043] Specifically, such as Figure 8 As shown, multiple input AC busbars 23 are vertically mounted on the mounting bracket 21 located at the rear of the power module 22. The power module 22 is connected to the input AC busbars 23 via the plug-in connector 212. The input AC busbars 23 are connected to the first input busbar 122 in the expansion distribution cabinet 1 via the first input interconnect 125. The output lines of the power module 22 pass through the first inlet port 118 and connect to the first output busbar 124, thereby realizing the input of electrical energy and forming a complete circuit. In this embodiment, the number and position of the first inlet port 118 correspond to the number and position of the power module 22.

[0044] In addition, multiple exhaust fans 24 are installed on the top of the first module cabinet 2 for overall heat dissipation of the first module cabinet 2.

[0045] like Figure 9 and Figure 10 As shown, when the expansion distribution cabinet 1 provided by this utility model is actually applied to a three-cabinet configuration, in addition to the first module cabinet 2 connected to its exterior, a second module cabinet 3 is also connected to its other side. The internal structure of the first module cabinet 2 and its connection method with the expansion distribution cabinet 1 are the same as those of the aforementioned dual-cabinet configuration. The structures of the first module cabinet 2 and the second module cabinet 3 are identical.

[0046] Unlike the dual-cabinet application scenario, in this embodiment, the power distribution component 12 of the power distribution cabinet 1 further includes a second input circuit breaker 126, a second input copper busbar 127, a second output circuit breaker 128, and a second output copper busbar 129. The second input circuit breaker 126 is installed side by side with the first input circuit breaker 121 on the front end face of the upper crossbeam 116. The second input copper busbar 127 is connected to the bottom of the second input circuit breaker 126 and is located near the second input port 115. It is connected to the second module cabinet 3 through the second input interconnection line 31 passing through the second input port 115, so that the power of the second module cabinet 3 is input from the second input copper busbar 127 to the expansion power distribution cabinet 1. The second output circuit breaker 128 is mounted parallel to the first output circuit breaker 123 on the front end face of the lower crossbeam 116. The second output circuit breaker 128 is electrically connected to the second input circuit breaker 126 (internal electrical connection lines are not shown in the figure). The second output copper busbar 129 is mounted vertically alongside the first output copper busbar 124 on the back side of the crossbeam 116. The bottom end of the second output copper busbar 129 is mounted on the lower crossbeam 116 and connected to the second output circuit breaker 128. The top end is mounted on the upper crossbeam 116 and connected to the output connector 117 located on the top of the housing 11. Electrical energy is transmitted from the second input circuit breaker 126 to the second output circuit breaker 128, and after passing through the second output copper busbar 129, it is output to the external DC load device through the output connector 117.

[0047] In summary, this utility model provides input ports on both sides of the expanded power distribution cabinet 1, and two sets of input and output power distribution structures can be installed inside the cabinet 1. When the expanded power distribution cabinet 1 is used in a dual-rack configuration, the input port on one side can be selected according to the actual scenario and connected to any set of internal power distribution structures to adapt to different site requirements. In high-power demand scenarios, the expanded power distribution cabinet 1 can be expanded into a three-rack configuration, with input ports on both sides and two sets of internal power distribution structures connected to the modular cabinet. This achieves the expansion effect without altering the overall structure of the expanded power distribution cabinet 1, resulting in a simple structure and convenient operation.

[0048] Although the present invention has been described and illustrated in detail with reference to preferred embodiments, the present invention is not limited to the disclosed examples, and those skilled in the art can derive other variations therefrom without departing from the protection scope of the present invention.
